Reaktionsschritte

2-Amino-4-(4-octylphenyl)butanol (30 mg), N,N-dimethyl-p-aminopyridine (52.6 mg), anhydrous triethylamine (34.2 μl) and anhydrous methylene chloride (1 ml) were mixed and the mixture was stirred under a nitrogen atmosphere at room temperature. Thereto was added (S)-α-methoxy-α-trifluoromethylphenylacetyl chloride (50.4 μl) and the mixture was stirred at room temperature for 10 hours. The reaction mixture was concentrated under reduced pressure and the residue obtained was purified by thin layer chromatography (eluent; chloroform:methanol=9:1) to give the two diastereomer mixtures. Moreover, the mixture was purified by high performance liquid chromatography (eluent; methanol:water=88:12, flow rate; 8.0 ml /minute) to give the subject oily substance (31.6 mg) of 67.8 minutes at retention time and the subject oily substance (31.9 mg) of 71.6 minutes at retention time.
